摘要
应用Ｘ射线衍射分析和穆斯堡尔谱学研究了Ｆｅ７３．５Ｃｕ１Ｎｂ３Ｓｉ１３．５Ｂ９非晶合金的纳米晶化过程．Ｆｅ７３．５Ｃｕ１Ｎｂ３Ｓｉ１３．５Ｂ９合金在５００～６００℃温度范围内分别退火１ｈ，可形成纳米ＤＯ３结构的ＦｅＳｉ相和剩余非晶相。随着退火温度的升高，有更多的ＦｅＳｉ相析出。在５００℃等温退火中ＦｅＣｕＮｂＳｉＢ合金出现二阶段纳米晶化过程。
The nanocrystallization process in Fe 73.5 Cu 1Nb 3Si 13.5 B 9 amorphous alloy was studied by means of X-ray diffraction and Mssbauer spectroscopy. After annealing for 1h at a temperature range of 500～600℃, The nanocrystalline FeSi grains with the DO 3 structure were formed and embedded in a remaining amorphous phase. The content of nanocrystalline FeSi phase increases with the rising annealing temperatures. Two different stages of nanocrystallization process in FeCuNbSiB al￣loy were found during isotherm alannealing at 500℃ .
